To alt whom it may Concern Y Be it known that IVJAMns H. MINER, acitizen of the United States, residing at Lumberton, Mississippi, haveinvented certain new and useful Improvements in lVheel-FlangeLubricators, of which the following is a specification.

My present invention relates to improvements in wheel flange lubricatorsdesigned to lubricate the flanges of railway cars, locomotives, streetrailway cars, and other vehicles running upon rails.

The invention has for its obj ect to provide an extremely simple andeconomical device which may be readily applied to the vehicle, and inwhich the lubricant may be easily and quickly replenished, and by whichthe lubricant will be constantly applied to the wheel flange with aneven pressure irrespective of the amount of lubrication.

With these and other objects in view the invention includes the novelfeatures of construction and arrangement and combination of partshereinafter described and particularly defined by the appended claims.

The invention is illustrated by the aid of the accompanying drawing inwhich the figure shows a car wheel in front elevation with thelubricator applied thereto.

Referring by reference characters to this drawing, the numeral 1designates the car wheel having the usual flange la and 2 a lubricantcontainer of open ended hollow or tubular form adapted to contain astick of lubricant 3, above which is placed a follower weight S. Thecontainer is designed to be suspended from any fixed part of the truckin proper relation to the wheel by any suitable means, as for instancebracket hanger 4. Within the container is located a leaf spring 5,preferably of U shape, with the bend 5a of the spring located in theupper end of the container and the extremity of one of its arms securedto the wall of the container. The other arm is adapted to bear on theweight 8 and by its contact oer frictional resistance to the movementthereof. When a fresh stick has been placed in the container its ownweight is such that less pressure of the follower weight is required tomove it forward by gravity than after it has been partly worn away. Myarrangement of spring is such that greater frictional resistance isoffered by the spring when the weight is near the bent portion 5a of thespring than when nearer the free end,

this being due to the fact that the farther away from the bend theweight gets the less pressure the spring would exert, the contact armspring being set so as to have a very slight incline away from the axisof the container.

ln order to adjust the pressure of the spring I provide a set screw 6passing through the wall of the container and bearing against the springa little way from its point of attachment.

In order to limit the inward movement of the weight and also to enableits withdrawal for the insertion of a fresh stick l connect it with theend of the container by a chain or other flexible element 7.

Having t-hus described my invention what I claim is 1. A wheel flangelubricator comprising an inclined hollow container for supporting alubricant stick movable by gravity in proximity to a wheel flange andmeans bearing against the side of said stick with a variable resistance,for compensating for the loss of weight in the stick as the same wearsaway.

2. A wheel flange lubricator comprising an inclined hollow container forsupporting a freely movable lubricant stick in proximity to a wheelflange, a follower weight for pressing on said stick and spring meanshaving a slightly inclined surface for bearing against said stick,

3. A wheel flange lubricator comprising an inclined hollow container forsupporting a freely movable lubricant stick in proximity to a wheelflange, a follower weight for pressing on said stick and a leaf springsecured in the container having a free lower end.

4l. A wheel flange lubricator comprising an inclined hollow containerfor supporting a freely movable lubricant stick in proximity to a wheelflange, a follower weight 10o for pressing on said stick, a leaf springsecured in the container having a free lower end for pressing againstthe side of the stick, and means for adjusting said spring.

5. A wheel flange lubricator comprising 105 an inclined hollow containerfor supporting a freely movable lubricant stick in proximity to a wheelflange, a follower weight adapted to bear against said stick, and a leafspring within the container and in fric- 11o tional contact with thesaid weight and having a free end in the lower part of the container andadapted to olfer less resistance to the movement of the Weight.

6. A wheel flange lubrieator comprising an inclined hollow container forsupporting a freely movable lubricant stick in proX- imity to a wheelflange, a follower weight in the container adapted t0 bear on the stick,and a two armed spring having the end of one arm secured approximatelycentrally of the container and the other arm in frictional Contact withthe weight, and means for varying the tension on the spring.

7. A wheel flange lubricator comprising an inclined hollow container forsupporting a freely movable lubricant stick in proximity to a wheelflange, a follower weight for pressing on said Vstick a leaf springwithin the container for offering frietional ref JAMES H. MINER.V
